FASTENER FOR PAPER BAGS A-ND THE LIKE.

Specification of Letters Patent. Applicatlonfiled November 20, 1911.Serial No. 661.858.

Patented July 29, 1 913.

To all whom it may concern,

Be itknown that I, ALAnaa TRAUB, a

residing at Vienna, Austria-Hungary, have invented new and useful Imirovements m Fasteners for Paper Bags an the Like, of

which the following is a specification.

The present invention relates to a fastener for-holding loose sheets ofpaper and the like parallel to the edge seized or to the folded edgeseized, which fastener is particularly adapted forsecuring the closureof paper bags, and will form a'reliable link for fitting a carrier,' forinstance for carrying the thus closed paper bag, or may be made to serveitself asa carrier.

The accompanying drawings illustrate several constructional 'forms ofthe invention and the manner it is employed.

Figure 1 illustrates oneform of the device. Fig. 2 illustratesa secondform. Fig.

2* illustrates a third form. Fig. 3 illustrates a fourth form. Figs. 4to 12 inclusive illustrate" diagrammatically the manner of applying thefastener to the paper. Fig. 13 illustrates a perspective View of a fifthform of the device.

In the constructional form according to Fig. l the fastener consists ofa piece of sheet metal drawn in form of a J, the longer leg 1 of whichhas its sides inwardly tapered to form two notches 2 in its sides, sothat it can be easily folded over the short leg 3. The edge of the shortleg is slightly hollowed out, so that points 4 are produced at thecorners,which points will enter into the paper and thereby facilitatethe securehold of the fastener. For the same purpose the edge isbesides. preferably provided with prongs or the like. This may also bethe case with the edge of the long leg 1.

Fig. 2 illustrates another modification, in which the bending over isfacilitated by the sheet metal being perforated at the place Where it isto be bent over. Both the edge of the long and thatof the short leg areserrated. The serrations and the edge of-the short leg are so arranged,that-when the fastoner is bent over. these serrations will penetratethrough the paper into holes provided in the metal. The grip of thefastener on the paper is thereby greatly increased. In

Here the short 1e and the lower part of thelong leg are provided up tothe bending line with corrugations, which extend beyond the jointbetween the two legs. The corrugations are impressed either during. orafter the bending into sha e of the two legs, preterably by the suita lyshaped die, .which prmluces the bend, impressing the corrugations intothe bent bend with a last pressure. These corrugations need, of course,not extend as far as the edge of the legs.

Fig. 3 is a constructional form, according to which the fastenerconsists of a wire frame likewise bent into the shape of a J.

Paper bags and the like are closed by means of the hereinbeforedescribed fast eners in the following manner: The edges of the mouth ofthe bag are laid together and introduced between the legs of thefastener (Fig. 4.) Now the edges of the paper are folded over the edgeof the short leg. This can be done in an easy and quick manner by thefastener being turned in the direction of the arrow, Fig. 4, until ithas the position in Fig. 5. Then the long leg is bent over the short onein the direction of the arrow in Fig. 5, whereby the closure iscompleted, Fig. 6. If a carrier is to be combined with the fastener, acarrier ring 6 may be inserted as shown in Fig. 6. Tu place of this ringof course also a loop or the like may be em-- ployed. The weight of theparcel will produce so great a friction between the paper and the edge 7of the short leg, that the edge of the bag will be securely held between the legs, which will be further as-' sisteddiy the action of thepoints 4. The

component P, Fig. 6, of the weight of the parcel will also produce afriction at the edges 8 and 9 of the bent over-fastener, so that therewill be no fear of the edges of the paper slipping out of the fastener.

It will be of advantage to. first fold over the edge of the bag beforethe fastener is fitted, as this will increase the friction andstrengthen the closure. The Figs. 7, 8 and 9 illustrate the operationsin making the closure. It will be still better to fold over --paper bagsto be closed but to. their comwhich may be bent over a s bag are in thefinished closure prevented by the double paper from tearing sharp edge10, Figs. 11 and 12.

In the modes of use in Figs. 7 to 12'the fastener is applied not to theedge of the at the Inon fold.

In the constructional form shown in Fig. 13 the fastener is formed so asto serve at the same time as a carrier for the paper bag closed with thefastener. The fastener is in this case preferably stamped of an endlessband of sheet metal so that the edges 1 and 13, at which the piece ofmetal is cut off from the whole band are of a congruent curvature, sothat the several pieces are stamped out of the whole without any waste.The piece of metal is then bent in the J- shape the same as with thehereinbefore described constructional forms. The portion 14 has a cut 11made in it by means of which out there is formed a long leg portion 12ort leg 13 in the manner hereinbefore described. The remaining ormarginal part of the portion 14 which is not bent over will form a sortof loop or carrier, by which the sheets of paper, the bag or the like,to which the fastener has been fitted, may be conveniently carried.

The edges of the cut 11 are preferably headed over, so as to removethesharp edge which would be inconveniently felt in carrying the parcel.

The essential feature common to all the hereinbefore describedconstructional forms .consists in that the papers to be united orcarried are gripped by a fold made over a sharp edge and held by thefriction produced thereby. This is above all obtained by means of theshort leg of the fastener,

. against the upper edge of which the paper is drawn the tighter, thegreater the load. The bending over of the upper ton ue is of lessimportance for obtaining this e ect; the tongue serves chiefly for theattachment of the carrier and is indeed of great importanceinconsequence of the simple and safe mannerof the attachment enabledthereby.

Claims: I 1. A combined fastener and carrier for paper bags and thelike, ccnsisting of a flat piece of metal bent intothe shape'of a J toform 'a pocket adapted to receive the edges of the mouth of a paper bag,a part of the long leg thereof being adapted to be bent over the paperto clamp the same between said part of the long leg and the short leg,the sides of said part being inwardly tapered at the bending line? theedge of the shortleg of said piece. 0 metal opposite to the bending linehaving a concave curvature and terminating in points.

2. A combined fastener and carrier for paper bags and. the likeconsisting of a piece of sheet metal bent in the shape of a J to form apocket, the long. portion of said of sheet metal' bent'in the shape of aJ p to form a pocket, the long portion of said piece of sheet metalhaving a U-shaped '1ncision forming a portion, adaptedto be bent overthe ed e of the paper to be introduced into the pociet formed by saidpiece of sheet metal, the remaining part of said long portion forming acarrier, the uppered e. of the short leg of said piece of sheet metahaving a concave curvature and terminating at the corners in points.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
